That's only about two and a half hours after the first shots rang out. At 2:46 a.m., investigator says Danley deleted her Facebook account altogether.

But it wasn't until 3:30 that morning, police actually revealed Stephen Paddock's name to the public.

Marilou Danley's quick response on her Facebook account doesn't necessarily contradict her claim of having no prior knowledge, but it does beg more questions: Was there any contact between the two the night of the shooting? What exactly did she know?
